The various parts of the blank shown in Figure 6 are folded with respectto each other to form, in connection with a pair of separablereinforcing members 15, a flat box section as shown in Figure 5. When soforming the section, the members 15 are seated on the end extensions6.with the latter extended in continuation of the body portion 3. Theextensions 5 are folded onto the sections 4, after which the latter arefolded to position the extensions 5 onsidemarginal portions of the bodyportion 8, in which position the tabs 12 extend across the reinforcingmembers 15 and flaps 7, and

the webs 9 are seated on the tabs 12 with the scores 11in registrywiththe scores 14-. The outer endaportions 16 ofthetabs 12 are thenfoldedunder along thescore lines 14 to extend such portions 16longitudinally of the reinforcing.members15; The-flaps;

7 then are folded 'inwardlyover-the webs 9 and the end portions 16 ofthe tabs 12.

The Various parts then aresecured'in their relative positions by a pairof staples or the "like i 171 at each end-of the. section; eachstaple'extending through a flap 7, endpor-r tion 16, reinforcing .member15, and end extensionfi. WVith the parts of the section arranged as:-aforesaid, allofsuch parts lie 'flat'avhereby a number ofthe sectionsmay be stacked in a minimum of. space for stor-- ing or "shipping.

When it 1s 'dGSlIGd to assemble one: of

the lowerzsections 2 with respect to a sec-- 1310 111 to form abox,theextensionsA, car-. rylng "the extensions 5 therewith, are swung.

outwardly to extendat right angles to the body portion 3; This" movementof the eX- tensions 4- causes the W8bSw9tO' be folded along their scores11 whereby :theportions 18 of the webs 9-operate as wedges beneath; theflaps-7 -to swing the extensions 6 in; wardly lnto positions at rightangles to thebody1'p0rtion 3,." This movement afurther 'causes the innerportions 19 of the tabs -12 to straighten out in continuation of :theouterportion- 16, in which position they are automatically locked bythemflaps-7 The section, withthe p'arts thereof arranged as aforesaid,'forms :'-one: 1 half *of" a box "-for as sembly with respect to; the:corresponding half ofzthe'box formed in the: same man-. ner; 1 If'it-eisdesired toreturnxth parts of the section'to their'originalpositions this may beacoomplished simply by grasping the end' extensions'6; centrally thereof; and swinging :the .same outwardly; This.

movement of :the extensions 6 causes the flaps 7 to release the tabs 12and further causes the'inner-portions 19 thereof to return to theirfoldedwpositions; while the folded iportions- 18-of the Webs 9 Uponreference to Figure '3 return I V it will be observed that the sideWallsofeach section of thebox.

It will be apparent that it is but the work of a moment toopenone of thesections to box forming position, as the only operation necessary tobewperformedby the operator is to graspwthez side extensions 4andswingthem; outwardly vwith respect to the body 1 portion:3. Likewiseit is but thewvork of" a moment-to return they parts of thesection to.their folded.positions,as the only-operation znecessary to-beperformedby ll-116901);

erator is to swing the end extensions 6 outwardly with=respect to thebody portion 3.-

Itis: thought; that themany advantages of paper boxes in accordancewithSthis 111-- vention'wwillbereadily apparent, and although the'preferred embodiment of the inventionis as-1llu'strated anddescr1bed,-1t 1s to,:be understood that rchanges in the size,
